This is a model of DNA, similar to the original ones made by Watson and Crick, the two scientists who discovered the structure of DNA. The different colors represent the four different bases: Adenine, Guanine, Cytosine, and Thymine.
These are the skulls of our genetic ancestors (left to right) Australopithecus africanus, 2.5 million years old; Homo rudolfensis, 1.9 million years old; Homo erectus, 1 million years old; Homo heidelbergensis, 350,000 years old; Homo sapiens, 4,800 years old.
If you don't get the joke, hopefully this website will help you understand. You're welcome.
